Grelka is a Nord merchant who resides in Riften. She is the owner of one of the stalls in the center of town and will sell you weapons, apparel and various other miscellaneous items. She has a starting amount of 750 gold to barter with. She also offers expert training in Light Armor. According to the Official Game Guide, she is the sister of Solaf and Bolund in Falkreath.

Grelka currently lives in Haelga's Bunkhouse. She starts off her day by waking up at 7am and has breakfast at the Bee and Barb for an hour. After that, she will work at her market stall at Riften Grand Plaza for a full twelve hours until 8pm. After selling items all day, she will return to the bunkhouse to have her dinner, and she has the rest of the evening free. At 1am, she goes to sleep for six hours and repeats her schedule the following day.

She seems neither a charitable or amicable person, evident in the things she says to everyone. For example, when Edda begs her for money, she will only give a "Go away." while Snilf will likewise receive "No. Now shove off." from her.

While she runs her stall, she will try to advertise her goods, saying, "Looking to stay alive? Why take a chance?", "Buy some armor and live to tell about it!", or "Protect yourself right... buy armor from Grelka." She will notice if you approach, though her tone will sour: "You going to buy something or just here for training? Otherwise, move on.", "You gonna stare all day or buy some armor?", or "Come on, come on. The sooner you buy, the sooner I can get drunk." Seeing her outside her stall will net you the same surliness: "Can't you bother me at my armor stand in the market? Or are you that desperate for training?" When you end your conversation with her, she will tell you, "Come back when you're ready to spend more gold... goodness knows I could use it."

When asked for Light Armor training, she will say, "I'll teach you how to use it effectively, and keep you quick on your feet."

You can complain about the way she treats all her customers, though it will be in vain: "Look, I've moved all over Skyrim selling these bits of junk and I'm barely scraping by. I'm not out to win friends and I could care less if you're happy about your purchase or not. I just need the coin. The sooner I get out of Skyrim the better." You can then ask her why she'd want to leave Skyrim, and she'll respond, "Are you serious? The war is tearing the land apart, the dragons have returned seeking who knows what... Skyrim is going nowhere fast. If I were you, I'd pack up and get out of here before you end up in one of those burial cairns."

If, on the other hand, you want to know more about the Ratway, Grelka will help you: "There are ruined sewer tunnels beneath the city. The only way I know how to get in there is through a door off of the canal. If I were you, I'd keep my feet dry and stay up here." You can also ask her about the Thieves Guild, and she will reply, "They'd stop at nothing to take your last bit of food if that's all you had. The Ratway's too good of a place for that scum."

Bolli: "Grelka, I wanted to talk about that suit of leather armor you sold me. The fasteners are already coming loose."Grelka: "Fine. It'll be five septims to repair it."Bolli: "Why should I pay for a repair on something I just bought?"Grelka: "All right, all right. Just bring it to me tomorrow and I'll fix it for you."

Mjoll: "Aerin tells me you might be dealing arms to the Thieves Guild. Is this true?"Grelka: "I don't know what he's talking about. He must be seeing things."Mjoll: "I'm watching you, Grelka. One slip up and I report you to the guards. You got that?"Grelka: "Whatever you say."

Grelka: "Did you do everything I said, Shadr?"Shadr: "Yes. The man came by at noon just like you said. I gave him the package and he gave me this pouch for you. The package was heavy... I needed his help getting it on his horse. What was inside?"Grelka: "Hey, I told you not to ask any questions. Now, here. For your trouble."Shadr: "Thanks, Grelka!"

Maven: "Grelka, how fast can you get your hands on some longbows?"Grelka: "I don't usually deal in weapons, but I know someone who can get them for me. You mind paying a little extra to get them fast?"Maven: "I don't care what it costs. I need four longbows and four score of arrows. Just make it happen."Grelka: "I'll contact my man tonight and let you know what he says."

Drifa: "Grelka, have you had anyone come by and try to sell you an iron war axe?"Grelka: "Not lately. Why?"Drifa: "Well, we had one go missing from the Pawned Prawn, and I was just wondering..."Grelka: "Oh I get it. 'It's missing so Grelka must have it.' I wish this town would stop pointing their fingers at me. There is a Thieves Guild in town you know."

Dinya: "Good day, Grelka."Grelka: "What's so good about it? I've got deadbeats who don't pay me, the city guard looking over my shoulder and Maven Black-Briar breathing down my neck."Dinya: "You poor thing. You should come by the temple, speak to Maramal."Grelka: "Religion isn't going to save me. So unless Mara is going to start raining coin from the heavens, why don't you mind your own business."

Tythis: "Grelka, can you repair boots?"Grelka: "Leather? If they're armored, you should talk to Balimund over at The Scorched Hammer."Tythis: "Horker skin, actually."Grelka: "Why in goodness name would you have... oh never mind, just bring them by my house later and I'll see what I can do."

Nivenor: "What's this nonsense I've been hearing? How dare you call Bolli a deadbeat!"Grelka: "If he paid what he owes, I wouldn't have to say anything. Besides, what in Oblivion do you care?"Nivenor: "What's that supposed to mean?"Grelka: "Oh come off it, Niv. We both know you married that fisherman for his gold. You don't need to put on an act for my benefit."

Grelka: "Oh, Haelga... there you are. Your special order from Hammerfell came in off the last Khajiit caravan."Haelga: "Oh, good. I wanted to try that out as soon as possible."Grelka: "Try it out? What would you need a leather harness for anyway?"Haelga: "It's a religious thing."

She will converse with her fellow tenants in Haelga's Bunkhouse:

Grelka: "So, Brand-Shei... business as awful for you as it is for all of us?"Brand-Shei: "Worse. The Khajiit Caravans are the only way to get supplies into the city, and even those are becoming more infrequent."Grelka: "Well, let's all raise a flagon to Ulfric; future King of Skyrim and bringer of poverty to the working class!"Brand-Shei: "Grelka! Lower your voice before you get us both in trouble."

Grelka: "Hey, greenskin... close your mouth. Some of us are trying to eat over here."Madesi: "There's no need to be rude, Grelka. If you don't care for Argonians, then perhaps you should take residence somewhere else."Grelka: "Or perhaps you should crawl back into whatever swamp you came from, lizard man."Madesi: "You're not going to goad me into a fight so I'll get kicked out, Grelka. Eat your food and leave me in peace."
